What's more shocking than the overall price tag, the Federation said, is that taxpayers contribute more than $23 for every one dollar an MP contributes to his or her own pension plan.

"(Taxpayers) are putting more money into the pension plan than they are actually paying MPs in salary every year," said Gregory Thomas, the group's federal director.

While backbench MPs earn $157,731 a year, Thomas said, an additional $248,000 is added to each of their pensions ever year by taxpayers, while they may contribute as little as $10,990.

The system has been rigged so that the MP pension plan -- which unlike the Canadian Pension Plan or RRSPs is not invested in the market -- pays itself a 10.4 per cent rate of return.

"It's a phony return set on an imaginary investment," Thomas said. "This rate means they basically have the best performing pension over 10 years on the planet ... It's probably the best pension plan on earth."

Next Monday, 39 MPs who were first elected in 2006 will pass the 6-year threshold to qualify for their parliamentary pension.

They will enter "the promised land" in the words of Thomas.

Together, the 39 MPs are set to collect $30.9 million in lifetime payouts, according to the federation.

Younger MPs such as 33-year-old Conservative MP Chris Warkentin and 38-year-old Industry Minister Christian Paradis will have to wait until they are 55 years of age to collect. But even if they don't run again, the Federation said Warkentin and Paradis will still receive an annual pension for the rest of their lives worth at least $46,049 and $61,581 respectively.

"People are walking away after six years on the job with a big payout for life. Starting at 55, a guaranteed index payoff, many of them in the multi-million of dollars," Thomas said.

Although the fictitious rate of return was set by cabinet, and MPs decide on the fate of their own finances through a small all-party committee that meets behind closed doors, the Federation called on the Conservative Government to turn off the taps.

"There is no way the Prime Minister and these MPs can do what they need to do to balance the budget and control spending if they have their own snouts in the pension trough. They need to lead by example, they need to put Canada ahead of their own personal bank balance," Thomas said.

He called for the immediate shut down of MPs' "platinum-plated pension plan" and the creation of a matching dollar-for-dollar defined contribution pension plan similar to the new registered pension plan, the PRPP, the government wants "all of us to adopt."

"If it's good enough for Canadians, it should be good enough for our MPs," Thomas said.
